The antibiotic puromycin kills both eukaryotic and bacterial cells because it:

A) binds to the rRNA that catalyzes the formation of peptide bonds and that rRNA is the same for eukaryotic and bacterial cells

B) can directly bind to any small ribosomal subunit

C) binds to the large ribosomal subunit and large ribosomal subunits are the same for eukaryotic and bacterial cells

D) resembles the 3ʹ end of a charged tRNA and tRNA structure is similar in all organisms

Solutions

Expert Solution

The antibiotic puromycin kills both eukaryotic and bacterial cells because it binds to the rRNA that catalyzes the formation of peptide bonds and that rRNA is the same for eukaryotic and bacterial cells.

reason: Puromyciin is very specific to inhibit peptidyl transfer. This transfer is same for both bacterial and eukaryotic cells
